code -2367 error?

[SPECTRE]

I am using LabVIEW-Multisim cosimulation to control a buck converter circuit. When I run the VI that controls the converter circuit in Multisim, I get a code -2367 error. Specifically, its this error:

External Model in buckconv.vi/Control & Simulation Loop<append>
 doAnalyses: Timestep too small

 (M202)

I think the error is with the simulation setting in Multisim, but I don't know what settings to modify so that I can fix the problem.

Hello,

Normally for a problem involving timestep scaling I would adjust the tolerance values. In your Simulation control loop, if you pull down on the bar to the left, there should be 2 options for tolerance (absolute and relative). Try decreasing the precision of these (instead of e-12, use e-08). Also the minimum and maximum stepsize control values are there as well so you could try chaning those. Let me know if that works.

Best Regards,
